Abstract
本实用新型涉及一种蓄电池组的不间断供电装置。蓄电池组在各行业都得到了十分广泛的应用，特别是当今的信息化时代，数字化时代，要求供电一刻也不能停。本实用新型的目的是让蓄电池组供电真正达到不间断。在交流断电的情况下，在蓄电池组中即使同时有一只或二只单体蓄电池失效损坏，仍能保证设备供电不间断。本实用新型如图1所示，主要由二极管C、接触片A、接触片B、弹簧D组成，接触片A连接蓄电池正极，接触片B连接蓄电池负极。当电池有故障阻抗变高时，二极管C由反向偏置变正向偏置，二极管导通达到续流的目的，若电流很大，二极管C发生性变或形变时，接触片A、B在弹簧的作用下紧密接触，短路此只电池仍达到续流的目的。
The utility model relates to an uninterrupted power supply device for a battery pack. Battery packs have been widely used in various industries, especially in today's information age and digital age, which require that the power supply cannot be stopped for a moment. The purpose of the utility model is to make the power supply of the battery pack truly uninterrupted. In the case of AC power failure, even if one or two single batteries in the battery pack fail and are damaged at the same time, the uninterrupted power supply of the equipment can still be guaranteed. As shown in Figure 1, the utility model is mainly composed of a diode C, a contact piece A, a contact piece B, and a spring D. The contact piece A is connected to the positive pole of the storage battery, and the contact piece B is connected to the negative pole of the storage battery. When the battery fault impedance becomes high, the diode C changes from reverse bias to forward bias, and the diode conducts to achieve the purpose of freewheeling. If the current is too large, when the diode C changes or deforms, the contacts A and B Under the action of the spring, the battery is in close contact, and the battery can still achieve the purpose of continuous flow after short circuit.
Description
Technical field:
The utility model relates to a kind of field of electronic devices.
Background technology:
Batteries has all obtained very using widely in every profession and trade, and the particularly current information age, digital times requires power supply can not break a moment.Even the instantaneous interruption of power supply also can cause tremendous loss or influence.In the past,, usually be a few group storage battery groups and connect power supply, still had generation even if the accident of power interruptions takes place like this in order to improve reliability.Reason is that all storage batterys all are in the floating charge state at ordinary times, and good and bad being difficult for of certain battery differentiated.In case AC dump enters the batteries discharge condition,, just can cause the power interruptions fault in battery pack as long as a battery damage (open circuit or internal resistance rising etc.) is arranged.Here it is, and current storage battery power supply still can not reach a main cause of real uninterrupted power supply.
Summary of the invention:
The purpose of this utility model is to allow the batteries power supply really reach uninterrupted.Under the situation of AC dump, damage even in batteries, have a joint or two joint cell batteries to lose efficacy simultaneously, can guarantee that still the power supply of equipment is uninterrupted.
The technical solution of the utility model is such: as shown in Figure 1, mainly be made up of diode C, contact chip A, contact chip B, spring D, contact chip A connects battery positive voltage, and contact chip B connects battery terminal negative.When battery has fault impedance to uprise, diode C becomes forward bias by reverse bias, diode current flow reaches the purpose of afterflow, if electric current greater than the diode rated value more for a long time, when diode C generation property change or deformation, contact chip A, B be closely contact under the effect of spring, and this battery of short circuit still reaches the purpose of afterflow.
Operation principle of the present utility model is such:
As shown in Figure 1, E is a batteries in the batteries among the figure.At ordinary times, the positive pole of diode C connects the negative pole of storage battery E, the positive pole of the storage battery that the negative pole of diode C connects, not conducting of diode reverse biased.Because the effect of diode C, contact chip A is also got out with contact chip B and is not contacted, and do not have influence to the operate as normal of storage battery this moment.Work as AC dump, when powering, if this joint battery malfunction by batteries, this moment, diode C added forward voltage, diode C conducting, and load current flows through diode C, if load current is no more than the rated load of diode C, diode does not damage, and keeps conducting always; If load current is greater than the diode rated load, diode generates heat, scaling loss or distortion, lose supporting role, contact chip A contacts closely with contact chip B under the effect of spring D, i.e. this batteries short circuit, be equivalent to remove the storage battery of inefficacy, thereby the power supply that guarantees this batteries is uninterrupted.If every battery of this battery pack adds that all this installs the purpose so no matter that battery damage can reach uninterrupted power supply.
Characteristics of the present utility model:
One, really accomplishes the uninterrupted power supply of batteries.
Two, the utility model is simple in structure, and cost is low, and is easy for installation.
Fig. 2 is the utility model embodiment behind the adding warning circuit.
G is the photoisolator of monitoring battery failure among Fig. 2, and export for alarm at M, N two ends, behind battery malfunction, and the elementary no current of G photoisolator, M, N become high resistant by the output low-resistance, thereby finish alarm.R is a current-limiting resistance, looks the nominal voltage of storage battery and selectes.
